由于更换服务器，不再支持Curl模块。所以决定使用Pear的HTTP_Request2包来更新更新Twitter。

原Curl代码:

$ch = curl_init($url);
if($postargs !== false){
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postargs);
}
if($this->username !== false && $this->password !== false)
curl_setopt($ch, CURLOPT_USERPWD, $this->username.':'.$this->password);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, $this->user_agent);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
$response = curl_exec($ch);
$this->responseInfo=curl_getinfo($ch);
curl_close($ch);
if(intval($this->responseInfo['http_code'])==200){
if(class_exists('SimpleXMLElement')){
$xml = new SimpleXMLElement($response);
return $xml;
}else{
return $response;
}
}else{
return false;
}

换为Pear::HTTP_Request2：

$req = new HTTP_Request2($url, HTTP_Request2::METHOD_GET);
$req->setHeader($this->headers);
if($postargs !== false){
$arr_post=explode("&",$postargs);
for($i=0,$imax=count($arr_post);$i<$imax;$i++){
$item_arr=explode("=",$arr_post[$i]);
$req->addPostParameter($item_arr[0], $item_arr[1]);
}
}
$req->setBody('');
$response = $req->send()->getBody();
if (200 == $req->send()->getStatus()) {
return $response;
}else{
return false;
}

下载解压HTTP_Request2来相同目录，如需测试，还需要下载Net_URL2和PHPUnit。运行AllTests.php显示如下：

PHPUnit 3.4.6 by Sebastian Bergmann.

.................................

OK (33 tests, 80 assertions)

表示安装HTTP_Request2正确。
